Filed:

Apr 19, 2002

Appl. No.:

10/125577

Inventors:

Venugopal Srinivasan - Palm Harbor FL, US
John C. Peiffer - New Port Richey FL, US
Daniel Nelson - Port Richey FL, US

Assignee:

Nielsen Media Research, Inc. - New York NY

International Classification:

H04N 9/00
H04N 7/16

US Classification:

725 9, 725 17, 725 19

Abstract:

Systems and methods for determining whether a television is on and in as near proximity are provided. An example system includes a sensor, an analog-to-digital converter, and a digital signal processor. The digital signal processor processes a set of digital audio samples detected by the sensor to determine if the sensor is in near proximity to a television in an on state.

Nielsen Media Research, Inc. - New York NY

International Classification:

H04H 9/00
H03M 13/00
G06F 11/00

US Classification:

725 20, 714819, 714799, 714815

Abstract:

An apparatus and method for processing audience measurement data detects and corrects one or more corrupted time codes. The corrupted time codes are identified by calculating a first set of intervals between a set of read times that may, but need not, be consecutive, each of which corresponds to one of the time codes extracted from a broadcast signal. The first set of intervals are compared to a second set of intervals between the time codes to identify when one or more of the second intervals do not meet a predetermined criteria. At least one of the time codes associated with each of the second intervals that do not meet the criteria is identified as being corrupted. The method used to calculate a corrected time code involves using the magnitude of the corresponding first interval to calculate the corrected time code.

International Classification:

G06K 9/00

US Classification:

382103, 382168, 348169

Abstract:

Methods and apparatus to count people appearing in an image are disclosed. One disclosed method reduces objects appearing in a series of images to one or more blobs; for each individual image in a set of the images of the series of images, represents the one or more blobs in the individual image by one or more symbols in a histogram; and analyzes the symbols appearing in the histogram to count the people in the image.

Assignee:

Nielsen Media Research, Inc. - New York NY

International Classification:

H04J 3/24
H04H 9/00

US Classification:

714704, 455 201

Abstract:

Methods and apparatus to extract audio codes are disclosed. An example method includes receiving signals on a plurality of channels and ranking the signals based on at least one characteristic of the signals. A first channel from the plurality of channels is selected based upon the ranking of the signals. The example method further include determining whether a first signal on the first channel includes at least one code and extracting the at least one code from the first signal when the first signal includes the at least one code.

Assignee:

The Nielsen Company (US), LLC - Schaumburg IL

International Classification:

G06K 9/00
H04N 7/16

US Classification:

382103, 382168, 382118

Abstract:

Methods and apparatus for detecting a composition of an audience of an information presenting device are disclosed. One disclosed method captures images of the audience, determines a number of people within the images and prompts the audience to identify its members if a change in the number of people in the audience is visually detected. This disclosed method avoids both under sampling of the audience and excessive prompting of the audience by only requesting entry of identification data when an audience change occurs. Methods and apparatus to determine the number of persons in an image or series of image are also disclosed.
